my son 27yrs experienced a very traumatic event three yrs. ago. Since then he is in bed all the time, became very forgetful, concentration very poor, has become withdrawn, does not engage with friends or socializing. He has no confidence, thinks people are talking about him, sleeps all the time when he does get up its at night mostly. He seems to do things backward, never cleans up after himself. Is there something wrong with him?
